Abstract: The present disclosure provides a system for supporting a movement of a moving body in a predetermined area. The system acquires an image captured by an infrastructure camera such that the image includes a plurality of markers arranged in the predetermined area. The system compares the image acquired this time and the image acquired previous time. The system detects a position change marker among the plurality of markers whose position in the image acquired previous time changes from that in the image acquired this time. The system determines that the infrastructure camera is out of position when it is detected that number of the position change marker is equal to or more than a predetermined number. The system determines that the infrastructure camera is not out of position when it is detected that number of the position change marker is less than the predetermined number.

Abstract: A dispensing device includes an air inlet hole passing through a cylinder in its thickness direction to connect an internal space of the container to an external space; and an action valve fitted onto an outer circumferential surface of the cylinder to close the air inlet hole, and that is isolated from the outer circumferential surface of the cylinder to introduce external air to the container when an internal pressure of the container is lower than an external pressure. An upper end portion of the cylinder is diametrically larger than a lower end portion. The action valve includes a ring-shaped annular section; and a valve section that extends axially from the annular section to close the air inlet hole while maintaining a radial clearance from the air inlet hole, to shield the air inlet hole from the internal space of the container.

Abstract: It is an object of the present invention to provide a foam dispensing container that can homogenize foam quality and can discharge foam of stable quality. By providing a plurality of liquid intake paths for delivering the foaming liquid into the air-liquid mixing chamber and a plurality of air intake paths for delivering air, the air-liquid mixing efficiency can be improved significantly, stable volumes of air and foaming liquid can be delivered into the air-liquid mixing chamber, without the possibility of delivering a great volume of liquid with a single press, and consequently the foam quality can be homogenized and foam of stable quality can be discharged.
